Banksia Ser. Cyrtostylis - According To George 1981

According To George 1981

In 1981, George published a taxonomic revision of Banksia in The genus Banksia L.f. (Proteaceae). He demoted Cyrtostylis to series rank, placing it within Banksia subgenus Banksia, section Banksia. It has remained at this rank since then, so its current name is Banksia ser. Cyrtostylis (Benth.) A.S.George.

George defined Cyrtostylis as those members of B. sect. Banksia with slender flowers, a small pollen-presenter, and beaked follicles. Its type species was given as B. media (Southern Plains Banksia).

George's 1981 placement and circumscription of B. ser. Cyrtostylis may be summarised as follows:

Banksia
B. subg. Banksia
B. sect. Banksia
B. ser. Salicinae (9 species, 5 subspecies)
B. ser. Grandes (2 species)
B. ser. Quercinae (3 species)
B. ser. Orthostylis (8 species, now B. ser. Banksia)
B. ser. Crocinae (4 species)
B. ser. Cyrtostylis
B. media
B. praemorsa
B. pilostylis
B. attenuata
B. lindleyana
B. ashbyi
B. benthamiana
B. audax
B. laevigata
B. laevigata subsp. laevigata
B. laevigata subsp. fuscolutea
B. lullfitzii
B. elderana (now spelled B. elderiana)
B. elegans
B. ser. Prostratae (6 species, 3 varieties)
B. ser. Tetragonae (3 species)
B. ser. Coccineae (1 species)
B. sect. Oncostylis (3 series, 21 species, 4 subspecies, 10 varieties)
B. subg. Isostylis (2 species)

A significant addition to the series occurred in 1988, when George published a new species, B. epica, placing it between B. praemorsa (Cut-leaf Banksia) and B. media.
